ELECTRICAL REQUIREMENTS
If codes permit and a separate ground wire is used, it is recommended that a qualified
electrical installer determine that the ground path and wire gauge are in accordance with local
codes.
Check with a qualified electrical installer if you are not sure the cooktop is properly grounded.
Make sure that the electrical connection and wire size are adequate and in conformance with
the National Electrical Code, ANSI/NFPA 70-latest edition or CSA Standards C22.1-94,
Canadian Electrical Code, Part 1 and C22.2 No. O-M91-latest edition, and all local codes and
ordinances.
A copy of the above code standards can be obtained from the following:

INSTALLATION REQUIREMENTS
Disconnect power before servicing.
Use 8-Gauge copper wire.
Electrically ground the cooktop.
Failure to follow these instructions can result in
death, fire, or electrical shock.
WARNING!

ELECTRICAL REQUIREMENTS (Continued)
Before You Make the Electrical Connection
To properly install your cooktop, you must determine the type of electrical connection you will
be using and follow the instructions provided for it here.
A 3-wire or 4-wire, single-phase, 120/240 volt, 60-Hz., AC-only electrical supply is
required on a separate, 40-amp circuit fused on both sides of the line. The model/serial
number rating plate is located on the metal cabinet underneath the cooktop. See the
following illustration.
The cooktop should be connected directly to the junction box through flexible, armored
or nonmetallic sheathed, copper cable. The flexible, armored cable extending from the
fuse box or circuit breaker box should be connected directly to the junction box.
Locate the junction box to allow as much slack as possible between the junction box
and the cooktop so that the cooktop can be moved if servicing becomes necessary in
the future.
Do not cut the conduit. Use the length of the conduit provided.
A UL-listed or CSA-approved conduit connector must be provided at each end of the
power supply cable (at the cooktop and at the junction box). A listed conduit connector
is already provided at the cooktop.
If the house has aluminum wiring, follow the procedure below:
a. Connect a section of solid copper wire to the pigtail leads.
b. Connect the aluminum wiring to the added section of the copper wire using
special connectors and/or tools designed and UL listed for joining copper to
aluminum.
Follow the electrical connector manufacturer's recommended procedure. Aluminum/copper
connection must conform with local codes and industry-accepted wiring practices.
